The programming and validating FEM code of Biot consolidation theory are used for analysis of the consolidation of composite ground with piles,and the consolidation behavior of the single pile composite ground and natural ground is compared.

• 在编制并验证Biot固结有限元程序的基础上,对群桩复合地基的固结变形及应力特性进行了数值模拟,并和单桩复合地基、天然地基进行了比较分析。 强排水群桩和单桩复合地基的固结特性差别不大;
